Output voltage high (1mA Sinking)
When an over-current condition happens, the
part will go into constant output current for this
time. After this time it will turn off the output
and pull low the PIN FAULT/. The MIC2090-1
and MIC2091-1 will automatically restart
themselves after the auto restart time
T
FAULT/ is connected to V
and 100pF in parallel. See “Timing Diagrams”
If the output voltage is greater than the input
voltage by this amount, the part will shut down.
The enable pin must be recycled to reset.
Time that the output voltage can be greater
than the input voltage before the chip is shut
down.
